Weaker vision in one eye should not be treated with eye drops without knowing the cause, because it may be due to refractive error (glasses number difference), cataract, lazy eye, retinal problems, optic nerve issues, infection, or glaucoma. Most causes of reduced vision are not corrected by routine eye drops. Lubricating drops such as Carboxymethylcellulose may help only if dryness or irritation is present. Please consult an ophthalmologist for proper vision testing and eye examination, especially if the weakness is increasing, sudden, associated with pain, redness, headache, flashes, or floaters.

Glasses help maintain clear vision and lessen eye strain, and a spectacle power of about 1.75 often indicates slight refractive error. If your eyes are adequate, stable vision can occasionally be restored using contact lenses or laser operations like LASIK. However, the number may not entirely go spontaneously, especially in adults. You should have a complete eye checkup before thinking about surgery to make sure your cornea is healthy, your power has been steady, and your eyes are otherwise okay. Steer clear of heavy screen strain, read in appropriate lighting, and get regular eye exams.
